ADX: Software Updates Capacity on demand with ADX License Activation

Feature Activation (v12.1)

– Used to enable premium features (e.g. Layer 3, GSLB)

Software Licensing (v12.2 and above)

– Includes feature activation used to enable premium features

– Upgrade licenses are now available for specific ADX platforms which

can be installed by customer

• Base licenses are pre-installed at the factory

With the v12.2 release the software licensing structure now

includes both feature and upgrade licensing capabilities for select

ADX platforms

ADX: Software Updates (cont.) ADX 1000 Capacity-on-Demand Licensing Model

The ADX 1000 family includes four base models of varying

processor and port capacity, based on the full ADX 1000 platform

hardware and operating system software

– ADX 1008-1 (1) application core and (8) 1 GbE ports

– ADX 1016-2 (2) application cores and (16) 1 GbE ports

– ADX 1016-4 (4) application cores and (16) 1 GbE ports

– ADX 1216-4 (4) application cores, (16) 1 GbE and (2) 10 GbE ports

ADX: Software Updates (cont.) Unlimited versus Trial Licensing

Two types of licenses supported

– Unlimited (perpetual and never expire)

– Trial (Only for Upgrade Licenses — 45 days)

Example Unlimited and Trial licenses for 1U

– ADX-1008-1-LIC-2PPLS (Perpetual License)

– ADX-1008-1-TRL-2PPLS (Trial License)

– ADX-1016-4-LIC-10G (Perpetual License)

– ADX-1016-4-TRL-10G (Trial License)

Web Management Enhancements Application Template and Software Upgrade

Generic HTTP Template

– Built-in generic HTTP Template which helps to facilitate the

configuration of HTTP Server Load Balancing

Code Upgrade through web UI

– Copy software image from TFTP Server

– Reboot the device

Additional ADX Feature Enhancements

SYN-Proxy support

6-6-4 and 6-6-6 Gateway support

RA based default route

Response Time Predictor

Transparent Cache Switching

SYN-Proxy Enhancement

In previous ADX releases, we offered line-rate SYN-attack

protection for IPV4 traffic. This has now been extended to the

protection of IPV6 traffic

– Enabling SYN-Proxy is the same as IPV4 — no new commands have

been introduced

– SYN-Attack is handled by hardware at line-rate

– Supports both 664 and 666 deployments

ADX RA-based Default Route Upstream Routers

IPv6 Router Advertisement (RA)-based alternative to VRRP1

Upstream routers send periodic RAs with different preferences

(high, medium or low); default value is medium

Set RA-interval to be a value lower than the required failover time

Response Time Predictor Enhancement Overview

Review : The ADX uses a parameter called the predictor to

determine how to balance the client’s traffic across the servers

ADX Connection Distribution policies:

– Round robin

– Least connections (default)

– Weighted distributions

– (Updated) Response time

– Response time/least

connections

– Least local connections

In previous releases traffic was always

sent to the server with least response time.

As of v12.2 the response time of the

server will be used as a dynamic weight

in load balancing decision.

Response Time Predictor Measurement of Response Time and Associated Weight

Based on response time of health check packets

– If Layer 7 Health Check is enabled, application response time

– If Layer 4 Health Check is enabled, SYN/SYN ACK RTT

Health Check must be enabled to make it work

The response time predictor is only applicable to TCP traffic (for

both well-known or non-well-known ports)

The load balancing decision is based on response time weight

instead of the actual response time

– Response time weights are derived from actual response time

measurement, the smaller the response time, the larger the response

time weight 1

Transparent Cache Switching (TCS) Enhancements Overview

Shared Layer 2 active-active TCS support

– Operates at Layer 2 and provides for two or more cache groups directly

attached split across the two ADXs

– Each uses all Caches in each group regardless of which ADX they are

connected to

– Traffic may be asymmetric across the ADXs because which route the

traffic may return is uncertain

– Sharing caches allows Link and ADX redundancy while utilizing all

available caches

Support an out-of-band SNMP-based polling mechanism to poll the

cache servers for their load information

– Vendor specific MIB is available

Summary

The Brocade ADX 1000 platform can be upgraded from entry level

to high-end with simple license activation

The Application Resource Broker enables on-demand provisioning

of application resources for private clouds

IPv6 to IPv4 gateway support allows for data center migration to

IPv6

The failover capabilities provided by IPv6 Router Advertisements

provide an alternative to VRRP deployment
